150 PRACTICAL FOREST MANAGEMENT. 



" It will be found that when the present crop is more mature ,. 

 the fellings prescribed will reduce the number of trees in each 

 group so largely that the forest will take on a more obvious 

 appearance of selection forest, consisting of groups of trees repre- 

 senting all age classes, with older trees having plenty of room to 

 develop large crowns and large increment. Even at present the 

 natural regeneration of oak is promising under the circumstances, 

 and the system of obtaining the regeneration by groups should 

 give it every encouragement, the nature of the fellings allowing 

 the marking officer every scope to obtain it, and putting nothing 

 in the way of the silvicultural necessities of the species. 



" Consistent with the system adopted, the marking officer is 

 given every possible latitude in carrying out the fellings, and 

 except that the annual yield is laid down by volume, only 

 silvicultural requirements will determine the extent of the cultural 

 operations in each compartment. 



" All trees above 8 * diameter have been enumerated and each 

 compartment has been described in the compartment history ; so 

 that the marking officer has a good knowledge of his growing stock 

 and the proportion of his age classes. When the stock has again 

 been enumerated after 10 years, a knowledge of the real increment 

 will also be available. " 



It will be thus seen that the latest practice in India conforms 

 very closely to the modified selection system used in Corsica for a 

 light -demanding species as explained in Chapter VI and is in 

 reality very different both from the theoretical selection system 

 which can still be used for a species like silver fir and the system of 

 removing mature trees by numbers which constituted in India the 

 so-called selection system so largely employed in the past. 



It is a live system allowing full play to silviculture and the 

 fellings are regulated by an exact calculation of the yield in volume ; 

 wh'ich yield may be realised from any diameter classes at the 

 discretion of the executive officer.
